坎地沙坦对慢性束缚应激诱导的大鼠抑郁样行为的作用

目的 观察坎地沙坦对慢性束缚应激(CRS)诱导的大鼠抑郁样行为的改善作用,探索抗抑郁治疗的新靶点。方法 雄性Wistar大鼠24只,随机分为3组:空白对照组(n=8)、束缚应激组(n=8)和坎地沙坦组(n=8)。通过旷场实验(OFT)、糖水偏爱实验(SPT)及强迫游泳实验(FST)评估大鼠抑郁样行为。用ELISA法检测血浆促肾上腺皮质激素(ACTH)及血管紧张素Ⅱ(AngⅡ)水平。结果 坎地沙坦组与应激组比较,OFT中直立次数及水平位移显著升高(P=0.000),SPT中对糖水偏好程度增加(P=0.027),FST中不动时间缩短(P=0.000),血浆ACTH明显下降(P=0.000)。结论...

Objective To observe the effect of candesartan on improving chronic restraint stress (CRS) -induced depression-like behaviors in rats and explore novel targets for the treatment of depression. Methods Twenty- four male Wistar rats were randomly assigned to control group ( n =8), stressed group ( n =8), and candesartan group (n=8), respectively. Open field test (OFT), sucrose preference test (SPT), and forced swimming test (FST) were performed to evaluate depression-like behaviors in rats. ELISA was used to detect adrenocorticotropin hormone (ACTH) and aniotensin Ⅱ (Ang Ⅱ) levels. Results Compared with the stressed group, rearing frequency and horizontal moving distance in OFT in the candesartan group significantl
